Magic: the Gathering Worlds Championships will be this weekend, and Standard is one of the formats they will be playing. As expected, the metagame of Izzet and Mono-Green as the top deck choices appeared in the decklists submitted by the participants. However, the Izzet Control deck gets a boost with the new version of the Grixis colors, and I think this is the best update of the deck ever. Having access to Black means spot removals and discard spells.
